A ground source thermal energy integration system

Abstract

The invention provides a ground source heat energy integration system. The ground source heat energy integration system comprises a ground source heat pump system, a heat exchanging system and an airconditioner system, wherein a ground source heat pump is connected with the heat exchanging system; the ground source heat pump and an air conditioner water chilling unit carry out refrigeration together; the ground source heat pump undertakes all air conditioner heat loads and hot water loads; the heat exchanging system comprises a heat exchanger, a circulation pump, a heat exchange valve and a main controller; an inlet water temperature sensor and a return water temperature sensor are arranged in an inlet water pipe and a return water pipe of the heat exchanger; an air pressure sensor and anexhaust valve are arranged in the heat exchanger; a heat exchanger system comprises a bearing platform heat exchanging system and a pile wall heat exchanging system; a foundation pile bearing platform is arranged below a basement bottom plate and makes direct contact with underground water; a bearing platform heat exchanger is buried inside the foundation pile bearing platform; a retaining pile wall makes direct contact with the underground water; and a pile wall heat exchanger is buried in the retaining pile wall. The ground source heat energy around a basement is fully used, noncondensablegas is exhausted through the exhaust valve, the condensation heat transfer coefficient is improved, and the heat exchanging efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ground source thermal energy, in particular to an integrated system of ground source thermal energy. Background technique [0002] Ground source thermal energy system is an effective energy-saving way of cold and heat source system. At the same time, this form of cold and heat sources does not emit pollutants during operation, which belongs to clean energy. In recent years, it has been widely used in various new and rebuilt buildings. However, the existing utilization of ground source heat energy is represented by simply extracting groundwater, surface water, buried pipes or energy piles. And did not make full use of ground source heat. [0003] Moreover, during the operation of the ground source thermal energy system, it is inevitable that non-condensable gases such as air and oxygen will enter the system, and then enter the downstream heat exchanger. If the steam contains air or other non-condensable...

Did not make full use of ground source heat

[0003] Moreover, during the operation of the ground source thermal energy system, it is inevitable that non-condensable gases such as air and oxygen will enter the system, and then enter the downstream heat exchanger. If the steam contains air or other non-condensable gases, the steam will flow in the heat exchanger After the surface condenses, the air will accumulate and form an air insulation layer, preventing heat transfer, even if the non-condensable gas content is small, the heat transfer coefficient will be greatly reduced
